The storage shelves are heavier than the compute node and should be installed as close to the bottom of the rack as possible.

Determine device order and cabling limits.

Install one set of rails. Then install the device. Do not install all of the rails at one time as you may not leave enough room for the devices.

Be aware of the depth of the rails and the devices. Ensure that the distance between cabinet posts accommodates the rails, devices, cables, extending ears, and PDU strips.

Hold a 1m SAS3 cable between the compute nodes and the Primary Storage Shelf and between the Primary Shelf and the last Expansion Storage Shelf. Visually confirm that the cables are long enough.
